Application filed December 18, 1897 Serial No. 662,465. [No specimens.)

T0 @ZZ whom, t may concern:

Beit known that we, THOMAS FOX NAYLOR and ARTHUR NAYLOR, subjects of the Queen of the United Kingdom of Great Britain and Ireland, residing at Green street, Kidderminster, in the count-y of lVorcester, England, have invented certain new and useful Improvements in Kidderminster, Scotch, or Ingrain Carpet Fabrics, (for which We have obtained British Letters Patent, dated June l5, 1895, No.11,692,) of which the following is a specification.

Ourinvention relates to an improved manu'- facture of Kidderminster, Scotch, or ingrain carpets, the obj ect being to use a smaller nu 1n-V ber of wefts than is usually employed. The ordinary carpet of this class is composed of two or more plies of weft-that is to say, having two or more Webs or layers of material thrown or shot bythe shuttle, which webs are bound together by the interweaving both of the Warp-threads and of the weft material. When weaving two-ply carpets of the class above named the shots of weft are placed alternately in the top web and in the bottom Web-that is, the iirst weft is shot into the bottom vweb (for example) and the second weft is shot into the top web, the third weft is then shot into the bottom, the fourth weft into the top, and so on, alternately, the one shot (or odd shots) being directly under the next shot, (or even shots, in the order just named,) except where they cross and recross by interweavin g in forming the pattern. Four shots of different-colored wefts are frequently used in the ordinary two-.ply carpet fabric of the aforesaid class, and the pattern or design thereof is produced by various combinations of the colors employed. Adverting to the aforesaid order of placing the odd numbers of the shots under the leven numbers and assuming the colors to be black, olive, scarlet, and White, they may be combined in the following manner: Black may be iirst shot in the bottom web, olive may be iirst shot in the top Web, scarlet may be second shot in the bottom Web, white may be second shot in the top web, and then repeat. The combinations used to give color effects are black` and scarlet, olive and white, black and White, and olive and scarlet; but in some cases black and olive are used as an additional combination.

Now our invention consists in making a Kidderminster, Scotch, or ingrain carpet hav-y ing two webs or layers of material thrown by.

the shuttle, but with one Web composed of one-half the number of shots of the weft material to that which composes the other web. The Web forming the face or upper side of the carpet has the larger number of weftshots, and in making the fabric two shots are placed in the top web to one in the bottom web. In the set of three shots, therefore, two shots would be placed side by side in forming the top web and one shot in the bottom Web; but the bottom-web shot is sometimes passed into the top web to form a part of the pattern, either in place of the first top shot or in place of the second top shot, While one of the latter takes its place in the bottom web.

Our improved manufacture of Kidderminster, Scotch, or ingrain carpet fabric is here inafter called a one-and-one-half-ply carpet.

In further description of ourinvention reference is made to the accompanying drawing, which is a longitudinal section of our said one-and-one-half-ply carpet, the Warpthreads being shown in an extended manner, while the top and bottom shots of weft are shown by circles indicating their transverse position in the fabric.

The figure denotes a one-and-one-half-ply fabric Woven with the ine Warp-threads l 2 Worked mainly around the weft-shots in the top web, but also occasionally passing from thence around the bottom wefts to make asolid cloth. The warp-threads 1 2 are black, for example, and are known as universal warp-threads from being used throughout the ground and the figure pattern. The thick lines 7 and 8 denote a stulfer and backing warp-threads of a different material, both ot' which form a substantial back and are Worked in the bottom web only, not appearing in the top web. The weft-shots are denoted by a for scarlet, b for olive, and c for black. The wefts a and c Vare first used, with the weft Z; beneath them. A change is made in the color combination by raising weft b to the top and lowering weft a, while a third color effect is produced by returning weft a to the top beside tlie weft b and placing weft c beneath IOO them. The upper and lower Webs are thus bound together by the interchange of wefts (which also produce change in the color effeet) and the passage of the iine warps 1 2 from the top web around a weft-shot in the bottom web once in each set of three shots of weft.

It is to be noted that the binder-Warps* that is, the warps used for binding the upper and the lower Webs together-may be vslayed so as to run two ends of warp in one reed close together in order to give a straight-line or ribbed effect, as in the ease of imitation-` Brussels carpets, or the binder-warps may be split, so as to produce an alternate or twilled efect,`as in certain other carpets known in the trade. Furthermore, we have used the term solid cloth above to denote the binding together of the upper and lower webs of the herein-described one-and-one -half ply carpet, as previously specified, and we restrict our claim thereto.

What we claim as our invention, and desire to secure by Letters Patent, is

In Kidderminster, Scotch, or ingrai n ear pets, a oneandonehalfply fabric consisting' of two layers of weft material formed by three shots of the shuttle, the upper layer having double the number of shots contained in the bottom layer, each one of the shots exchanging positions at intervals with one of the remaining two shots to form pattern or color effect, combined with two fine Warp-threads worked mainly around the shots in the upper layer but passing from thence once in each set of three shots of weft to the bottom layer and back again to bind the said layers together, and two thicker warp-threads continuing in the bottom layer to form a backing, substantially as and for the purpose herein described.

In testimony whereof we have signed this specilication in the presence of two subscribing witnesses.

THOMAS FOX NAYLOR. ARTHUR NAYLOR.
